Application led- September 29, 1923. Serial'No. 665,598.

f To all whomiz't may con-cern Be it known that' I, STANLEY P, HiCKni, a citizen of the United States, and resident of township of Coldspring, in the county of Jefferson and State of Wisconsin, have invented certain neiv and useful Improve- 'inents in' Auxiliary Wheel Treads; and I do hereby declare that the following is a lo full, clear, and exact description thereof.

treads, and has primarily for its object to provide a tread designed for use in connection with pneumatic tired Wheels, whereby, upon deflation of the tire, the Wheel is supported upon the auxiliary tread.

.Due .to present congested conditions on highways, which often makes vit impossible and dangerous to attempt repair or changing of a deiated tire, and theu fact that a large number of vehicles are operated by Women and persons incapable of effecting immediate repairs, vehicles are often run a considerable ldistance upon deflated tires, with the result of serious damage to the tire, and in some instances to the-rim and Wheel structure. y

The object, of the present 4invention is, therefore, to overcome the foregoin and provide4 an auxiliary'tread which Wil permit vehicles to be driven forshort distances 4to a garage or repair station Without damage to the deiated tire or otherparts of the vehicle. v

A further advantage and object ofthe' present invention resides in its use as a l guard or protector against stone-bruises result'mg from running` over stones, railroad tracks, or engaging 'the sharp ed es of-curbstones'or other obstacles, when t e tires are only partially deflated.

A more specific object is to provide a device of the foregoing character, which may be constructed in the form of an attachment for vehicle `wheels of conventional structure, thereb eliminating special vdesign oralteration o Wheel structure.-

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement* of parts, substantially as hereinafter described and more particularly defined by thea pended claims, it'beiiig understood that suc wThis invention relates to auxiliary wheel the present invention attached thereto.

changes in the precise embodiment of the herein disclosed invention mav be made as come within the scope of the claims.

k -In the accompanying drawing is illusti'atd one complete example of the physical embodiment of the present invention con- Structed according to the best mode so far devised for the practical application of the principles thereof. f

vThe single vievv is a transverse section through a conventional vehicle Wheel with Referring more particularly to the accompanying drawings, the present invention is` shown in connection with -a conventional Wood vehicle Wheel comprising a felloe. l, provided With the felloe band 2, upon Which is mounted a demountable rim 3 of the conventional straight side type. The rim 3 carries a pneumatic tireocasing 4 of any desired structure.,

For the purpose of illustrating one form in which the present invention may be de'- signed, I have shown an auxiliar rim positioned adjacent the casing 4, W. ich rim is provided with inwardly extending spaced arms 6 which carry an annular plate 7 80 adapted to be secured to the side of ther felloe 1 by means of bolts 8 passing therethrough.

Mounted on the auxiliary rim 5, either directly, or preferably as shown, is a resilient tread- 9 formed of rubber7 or other suitable material, and rovided With the retaining band 10 which is locked on the auxiliary rim by means of the. screws 11 which pass .through the depending lugs 10 on the re- 00 taining band andare threaded into bosses 12 spaced at. suitable intervals throughout 'the rim 5.

As illustrated in .the diy'awing, the tread 9 is of considerably smaller diameter than 95 the tread of the casing @when the latter is inflated, thus, under normal conditions, permitting the vehicle to travel on the tire, and because .of the spaced relation between the casing 4 and the tread 9, the free action, 100' or `flexing of the casing, is in no Way interfered with.

In-the'event that the casing 4 becomes de- Hated, as the result of a puncture or blowout, the same will be collapsed to a point where the auxiliary tread 9 will engage the `Vroad and relieve the casing of any further strain resulting from the Weight of the vekhiel'e.

f Attention is further directed to the fact that in spacing the tread 9 from the casing 4, the accumulation of dirt and other may erial between the two is avoided. `Should4 mud, sand, or snowsT be encountered, it is' obvious that When the casing 4 becomes embedded tlierein to a certain depth, the tread 9 will not only serve as an additional traction means, but Will also prevent further einbedding. s

While I 'have illustrated and described one torni of constructing the present inventionk and attaching the saine to a conventional type of `Wood vehicle frame, it is to he understood that various structures are contemplated within tlie invention, whereby the auxiliary tread may be readily attached to Wheels ot various types; such as disc or' wire Wheels.

Further, instead of constructing the deyice in the form ofV an attachment torreon-v Ventional structures of Wheels, it will be readily appreciated that the same may form a built-in partei the Wheel structure.
